Blast
An optimistic L2 that natively yields ETH (via Lido) and stables (via T-bill exposure) to bridge depositors.
Blast went live in 2024 with native yield as its differentiator: bridged ETH auto-stakes via Lido; bridged stables earn T-bill yield via a Reservoir / Centrifuge-style RWA wrapper. The "auto-yield" framing has been controversial — under the hood it adds counterparty risk to bridged assets.
